Abstract
The interface reations between SiO2–PbO melt and Mn‐Zn ferrite were studied using electron probe microanalysis (EPMA) and X‐ray diffraction (XRD). Intermediate layers were formed at the interface between the glass and the Mn‐Zn ferrite which were heated at 800° and 900°C, although those layers were not found in specimens heated at 1000°C. Using EPMA and XRD, the intermediate layers were found to be Pb2(Mn, Fe)2Si2O9 and Pb8(Mn, Fe)Si6O21. The mechanisms of interface reactions are discussed, related to glassforming regions. It was concluded that the interface reaactions between SiO2–PbO melt and Mn‐Zn ferrite are controlled by the dissolution of Zn ions and Mn ions from the Mn‐Zn ferrite.
